How Much Does a Jin of Yellowhorn (Xanthoceras sorbifolium) Seeds Cost? A Detailed Guide to Common Disease Prevention and Control Methods

Xanthoceras sorbifolium is an edible oil tree species unique to China, and it was once cultivated on a large scale in the north and northeast. So how much does a jin of Xanthoceras sorbifolium seeds cost? What are the common diseases and their prevention and control methods?

1. How much does a jin of Xanthoceras sorbifolium seeds cost?

Xanthoceras sorbifolium can generally be propagated by sowing, division, layering and root cuttings. If propagated by seed sowing, it can be done in spring, summer and autumn, with a seeding rate of 20-30 per mu. At present, the price of Xanthoceras sorbifolium seeds on the market ranges from 70-90 yuan, and the price is generally higher during the planting peak season or when production is low.

2. What are the common diseases of Xanthoceras sorbifolium and their prevention and control methods?

During the planting process, the occurrence of pests and diseases is one of the important factors affecting product quality and yield. Severe pest and disease conditions can even lead to the death of plants over a large area, causing huge losses. Therefore, a brief introduction to the common diseases of Xanthoceras sorbifolium and their prevention and control methods is given below.

(1) Common diseases of Xanthoceras sorbifolium and their prevention and control methods

1. Chlorosis: Strengthen management at the seedling stage and carry out timely intertillage and loosening of the soil; remove diseased plants; implement crop rotation; and carry out plowing and air-drying of the soil in the woodland.

2. Damping-off: Spray with 75% chlorothalonil wettable powder at 600 times dilution, or 5% validamycin aqueous solution at 1500 times dilution, or 20% tolclofos-methyl emulsifiable concentrate at 1200 times dilution.

3. Sooty mold: First, strengthen management at the seedling stage and carry out timely intertillage and weeding. At the same time, choose carbendazim at 800 times dilution and spray continuously 2-3 times with an interval of 7-10 days. In early spring, spray 50% dimethoate emulsifiable concentrate at 2000 times dilution.

4. Root rot: Usually choose folpet at 400 times dilution for spraying control, and zineb at 500-900 times dilution can be sprayed for control.

(2) Common insect pests of Xanthoceras sorbifolium and their prevention and control methods

1. Black velvet chafer: During the larval stage, 50% phoxim emulsifiable concentrate can be sprayed for control, with a dosage of 3.75 kg per hectare. Before the adults emerge from the soil, 40% diazinon emulsifiable concentrate should be sprayed for control. After entering the adult stage, spray 50% fenitrothion emulsifiable concentrate at 1000 times dilution for control, or alternatively use 80% dichlorvos emulsifiable concentrate at 100 times dilution for control.

2. Root-knot nematode: In winter, loosen the soil and expose the roots, dig deep into the soil near the roots under the tree canopy of diseased plants, prune off the root system damaged by root-knot nematode disease, and promptly remove the diseased roots from the orchard and burn them in a centralized manner.

3. Psyllids: (1) Clear fallen leaves and weeds in the woodland to eliminate overwintering adults. In early spring or at the initial stage of occurrence, spray 5 degrees Baume lime sulfur mixture, 2.5% beta-cypermethrin emulsifiable concentrate at 2500 times dilution, or 25% lambda-cyhalothrin emulsifiable concentrate at 2000 times dilution for control. (2) Spray the leaf surfaces (both sides) and the tree body with 10% imidacloprid water-dispersible granules WG at 15000 times dilution, 3% acetamiprid emulsifiable concentrate EC at 2000 times dilution, 1.8% abamectin emulsifiable concentrate EC at 3000 times dilution and other pesticides.

4. Aphids and scale insects: Usually spray dichlorvos at 1500 times dilution for control, or alternatively use rosin mixture or petroleum emulsion at 10-20 times dilution for spraying.

Pests and diseases of plants are related to yield, quality and growth vigor, so during planting and management, they must be discovered and treated promptly to reduce losses as much as possible.
